Animal feeding stuffs: Methods of sampling and analysis. Determination of OCPs and PCBs by GC/MS1 Scope This document specifies a gas chromatographic mass spectrometric (GC MS) method for the determination of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in compound feeds and feed materials (oils and fats, fish meal). The method is applicable to compound feeds consisting of less than 20 % water by mass and oil fatty samples containing residues of one or more of the following OCPs and PCBs and some of their isomers and
